Randomization description
In this study, the permutation blocks method was used to generate the sequence of random assignments of people to the studied groups. A random allocation sequence of people was done using Random Allocation Software and a block size of four. The permutation block method is one of the random allocation methods in which each block is selected as an integer multiple of the number of studied groups. In this study, there are four blocks: AABB, ABAB, BBAA, and BABA. One of the blocks is randomly selected. If the first block, AABB, is selected, the first and second person will be assigned to group A, and the third and fourth person will be assigned to group B. And this process continues until all samples are allocated. The feature of this method is that the two study groups will have equal numbers. Random Allocation Software is free software for creating a random sequence using scientific methods including the permutation block method for allocating subjects to treatment groups, which was developed by Dr. Mahmoud Saghaei (https://www.saghaei.net).
